Both my model and skill.json are up to date when I check `ask diff`, I made some changes to the lambda function in `index.js`, and when I tried to `ask deploy`, I got this error message:
[Error]: Failed to resolve the Lambda deploy state for arn:aws:lambda:xxx. Please make sure this Lambda resource is correctly mapped to the existing alexaUsage in the config file.
My understanding is that the `config` file is populated automatically and I didn't make any change to it... I'd appreciate it a lot if someone can help me understand this error.
